It is a genually good game, but not perfect in my opinion. The combat and roleplay adaptation from DnD is well executed, but controlling 4 characters (plus summons) can be pretty exhausting considering spell casters can get easily to 30~ different actions between weapon attacks and spells.
The HUD needs more work in my opinion. I used a controller because otherwise the HUD was pretty small, and I felt the inventory managing to be slow sometimes and the combat radials to be messy, even if you try to reorganize the dials from time to time.
I found a concerning amount of bugs, which I guess will be fixed with time but they were annoying. One of them prevented me (without knowing) of romancing Karlach and that made me pretty pissed.
In general, the quests (optional or not) give you a lot of freedom. Most quests have different conclussions and you can achieve them, sometimes, in creative ways. This makes the game more fun, but almost all of the time you will be using standart violence, so don't get used to it.
Overall, a well developed tactical RPG, but it has room for improvement. If you have the time and eagerness to fully embrace the lore, characters and fights that the game provide, you will have a good time.
